    摘要: System and method of photoaltering a region of a material using a pulsed laser beam. The method includes scanning the pulsed laser beam in a first portion of the region with a first pattern, scanning the pulsed laser beam in a second portion of the region with a second pattern, and separating a flap of the material at the region. The system includes a laser, a controller selecting at least first and second patterns, and a scanner operable in response to the controller. The first pattern has a first maximum acceleration associated with the second portion, and the second pattern has a second maximum acceleration associated with the second portion. The second maximum acceleration is less than the first maximum acceleration. The scanner scans the pulsed laser beam from the laser in the first portion with the first pattern and in the second portion with the second pattern.

    摘要: A method of photoaltering a material using a pulsed laser beam includes selecting a first pulse energy and a first focal point separation based on a relationship of pulse energy and focal point separation combinations enabling layer separation of the material by photoalteration, and scanning the pulsed laser beam along a scan region at the first pulse energy and the first focal point separation. The relationship has a slope and has a distinct change in the slope. The distinct change in the slope is associated with a second pulse energy of the relationships and the first pulse energy is equal to or less than the second pulse energy.

    摘要: A system for adaptive laser scanning correction includes a laser scanner coupled to a controller. The controller develops control signals for the laser scanner for a directed scan pattern that is modified to compensate for a characteristic scan-pattern distortion introduced by the laser scanner. The laser scanner responds to the control signals to provide an actual scan pattern approaching a target scan-pattern shape. The system may be useful for ophthalmologic laser surgery and other applications requiring precise control over scan pattern shape and a high scanning speed.

    摘要: A system for laser amplification includes a dual-crystal Pockels cell which is used to control emission of laser pulses from an ultra-fast laser. The Pockels cell is constructed to enable adjustment of the rotational orientation of one crystal relative to the other crystal. The rotational orientation of one or both crystals in the Pockels cell is adjusted to control sidebands in the laser pulse.

    摘要: System and method are disclosed for in-situ monitoring of a specimen while undergoing a defined process. The system includes a processing system adapted to perform the defined process on the specimen, and a coherent anti-Stokes Raman scattering (CARS) microscopy system adapted to in-situ monitor the specimen. In another aspect, the CARS microscopy system is adapted to in-situ monitor the specimen simultaneous with the defined process being performed on the specimen by the processing system. In still another aspect, the CARS microscopy system is adapted to perform a measurement of the specimen while the defined process being performed on the specimen is paused or temporarily halted.
